Always a one-sided story
Sure, it could be true. But it could also be an issue of people who got it into their head that they 'deserve' a positive promotion and will now start blaming everything except themselves.
I think people sometimes get it into their head that they're entitled for things like a promotion, but fact of the matter is that you're entitled to getting paid to perform the job for which you've been hired. It is awesome if you get promoted and rise up in the ranks, but it's most certainly not the companies obligation to even do so.
And I think that last part is what some people tend to forget sometimes.
